The methodology is based on singular perturbed techniques to take into account the slow behavior of degradations. The full-order system is firstly decoupled into slow and fast subsystems. An interval observer is designed for both subsystems under the assumption that the measurement noise and the disturbances are bounded. Then, the degradation is modeled as a polynomial whose parameters are estimated using ellipsoid algorithms. Finally, the RUL is predicted based on an interval evaluation of the degradation model over a time horizon. A numerical example illustrates the proposed technique. © 2016 ISA |

This involves following the migration of a colored tracer, with flow properties identical to that of the bulk using tracer detection by image analysis. The particle transitions from all initial tracer positions inside the mixer are calculated and the experimental conditions are established which improve the homogeneity of the mixture. Finally, a Markov chain model is derived which gives a good representation of the experimental data. © 2002 Elsevier Science B.V. All rights reserved. |
